Reducing bias in eyewitness sketches

In a contribution to TODAY's Science section, Associate Professor Terence Sim from the Department of Computer Science writes about his project to combine psychological insights with image analysis algorithms to tackle the challenging problem of identifying suspects and criminals through face sketches. By studying how humans perceive and remember faces, he argues that he has devised a novel method to first elicit the face sketch from a witness’ memory, and then to match the sketch against a criminal database of photographs.
